I'm doing a load of work to my new rst s2. Just rebuilt the gear box,front end stripped and rebuilt etc. While the box is off i thought i might as well replace the clutch. On taking the thing off i noticed the flywheel face covered in ripples and black scuff marks etc so defo needs sorting out before the new clutch goes on (cant see the ap unit lasting long like it is).

Now i'm guessing its the original flywheel and not sure if its been refaced before but where the clutch plate sits it has worn slightly into the wheel.

If i have it refaced would it reduced the final clamp pressure due to the recess in the flywheel?
Or
Do i replace it in which case does anyone know how much a new genuine one costs?
